Cannot find module: internal/modules/cjs/loader.js:969

I wanted to run my app and I suddenly got this error. Why?

this is what my order looks like in which i work.

./
├─ app.js
├─ .env
├─ .gitignore
├─ node modules/
│  └─ ...
├─ package.json
├─ package-lock.json
├─ models/
│  └─ advertiser/
│     └─ advertiser_info.js
├─ customer
└─ db/
   └─ advertiser_db.js

app.js:

const express = require("express");
const app = express();

/* ******** Database Connection ********* */
var db = require("./db/advertiser_db");


db.sequelize.sync().then(() => {
    console.log("Database connection successfull");
    app.listen(process.env.PORT, () => {
        console.log("Express listening on " + process.env.PORT);

    })
});

db/advertiser_db.js:

require("dotenv").config();
const Sequelize = require("sequelize");
const sequelize = new Sequelize(`${process.env.DB_NAME}`, `${process.env.DB_USERNAME}`, `${process.env.DB_PW}`, {
    host: `${process.env.DB_HOST}`,
    dialect: "postgres"
});

const db = {};

db.n_advertiser = sequelize.import(__dirname + "/models/advertiser/advertiser_info.js");
db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;

models/advertiser/advertiser_info.js:

module.exports = (sequelize, Sequelize) => {
    return sequelize.define("advertiser", {
        blabla: {
            type: Sequelize.STRING,
            allowNull: false,
        },
        blabla: {
            type: Sequelize.STRING,
            allowNull: false,
        },
        email: {
            type: Sequelize.STRING,
            allowNull: false,
            validate: {
                isEmail: true
            }
        },
        hashedPw: {
            type: Sequelize.STRING,
            allowNull: false
        },
        blabla: {
            type: Sequelize.STRING,
            allowNull: false,
        },
        blabla: {
            type: Sequelize.STRING,
            allowNull: false
        },
        blabla: {
            type: Sequelize.BOOLEAN,
            allowNull: false,
            defaultValue: true,

        }
    })
}

If i Run the app.js file i see this errors:

internal/modules/cjs/loader.js:969
  throw err;
  ^

}

i saw that it shows me a path that doesn't exist at all. Why? I have never defined that path: '/Users/yildirim/Desktop/nn_backend/db/models/advertiser/advertiser_info.js'

thanks for your helpful answers.
